培育优质高产水稻品种是当前水稻育种的重要任务之一; 胶稠度是稻米蒸煮食味品质最重要的指标之一。 传统的化学法测定稻米胶稠度, 前处理复杂、 过程繁琐、 试剂消耗多, 难以满足大批量水稻品种(组合)胶稠度快速无损检测的需求。 近红外光谱分析能快速、 无损、 无污染地分析检测。 以137份南方稻区主栽或新育成的籼稻品种(组合)为供试材料, 用传统化学法测定其稻米胶稠度并收集其近红外光谱, 以建立南方籼稻米胶稠度近红外光谱分析模型, 并对模型进行校正、 检验。 用偏最小二乘法(PLS)分别经20种数学预处理和6种波长段(或组合)建立各自的近红外分析模型。 通过比较模型评价指标确定了平滑预处...

Cultivating high-quality and high-yielding rice varieties is one of the important tasks of current rice breeding, and gel consistency is one of the most important indicators of rice cooking and eating quality. The traditional chemical method for measuring the gel consistency of rice has complicated pretreatment, complicated process, and high reagent consumption. It is difficult to meet the needs of rapid non-destructive testing of the gel consistency for large batches of rice varieties (combinations). The near-infrared spectroscopy analysis tec...
